To all whom 'it may concern:

Be it known that I, HERBERT L. JOHNSTON, a citizenof the United States,residing at Troy, inthe county of Miami-and State of Ohio, have inventedcertain new and useful for Umbrella-Ribs, of which the followin"y is aspecification.

The inventionI/(lates to improvements in tips for umbr l a ribs.

The objet/f the invention'is to provide a simple ang/ effective devicefor securing the fabric co/'er of the umbrella to the ribs in a mannerwhich will permit the ready removal of the cover when desired but at thesame time effectuall)v secure it in place when in position.

The invention consists in the constructions and combinations of scribedand set forth in the claims.

'In the accompanying drawings, I4`igure 1 is a verticalV sectional viewon -an enlarged scale of a device embodying my invention, a portion ofthe cover and rib being shown in position therein. Figs. Q and 3 areperspective views of parts of the device. Fig. 4 is a modified form ofsleeve. v

Like parts are represented by similar characterso'f reference in theseveral views.

The tip consists essentially of a cap, a, formed of sheet. metal, and a.sleeve, also of sheet metal. .The sleeve is preferably formed ofresilient nature and provided with a longitudinal slit, l, on one sideand with a liaring'end, 712. v The sleeve, however, may be, if desired,formed of a solid non-.resilient nature. A

In assembling the parts, the fabric of the cover c is placed over theopen end of the cap and the flared end of the sleeve pressed into thesame so that the fabric will lie between the sleeve and the cap. ..\ninternal bead, al, is then formed on the cap by pressing themetal in, asind- :ated in the sectional view, thus securing the fabric between thesleeve and cap at-tbis point. '.lhe distance between diametricallyopposite points ou the bead will preferably be slightly less than thepart` of the sleeve so as to provide an interlocking conn'cctioubcvtweenthe two parts, and thus prevent the sleeve from working up outof the cap or the cap' from slipping oftl the fabric about the rib. Thisdistance, however, might be substantially the same, or even less, thethickness of the fabric between the. bead and parts hereinafter dethesleeve forming in effect an enlargement of the bead. When the bead 1smade 1n the outer cap it will 4cause the resilient sleeve to becontracted more or less, lbut when the rib, cl, is inserted the sleevewill spring out to accommodate itself to the size of the rib and alsowill beI caused to be impinged more firmly against the bead and thusmore tightly) secure the fabric in position. After the ri is inserted inplace the head thereof will serve to hold the fabric against the bottomof the cap and draw the same taut between the head and the flaredportion of the sleeve, and thus further tend to secure the partstogether'.

When a non-resilient sleeve is employed, the fabric will be clampedsecurely between the bead, a', of the cap and the rsolid wall of thesleeve. In this case the sleeve will always beA made large enough toaccommodate the largest size rib.

Having thus described claim 3. In a device of the cha- 'acter described,a cover, an outer cover-receiving member, an inner rib-receiving'member. inserted therein, and au internal and external projectingportion on thel respective members between which thc. cover lies formingan interlocking joint, substantially as specified.

In a device of the character described, a cover, an outercover-receiving member open at one cud, an inner open-ended'ribreceiving member insertiblc within said outer member, said coverbeing located between said members an internal projecting portion onsaid outer member adapted to clamp the cover to the inner member, and anexternal projecting portion on said inner member lying within said outermember and beneath the internal projecting' portion thereof,substantially as specified.

2'. ln a device of the character described,l a cover, an outercover-receiving member open at one end, an inner open-ended ribreceiving member insertible within .said outer member, Isaid coverheilig located between said members said inner member being formed witha longitudinal slit and being of resilient material, an internalprojecting portion on said outer member, and an external projectingport-ion on said inner member lying within tbc outer member and beneaththe internal projecting thereof, substantially as specified.l

port-ion lio 4. In a device of the characterdescribed,

a cover, an outer cap, a sleeve inserted therein having a flaring end,and an internal rib 'in said cap above said flared end of the 5 sleeveadapted to clamp the cover to the sleeve, substantially as specified.

5. In a device of the character described, and in combination with thefabric cover and rib, of an outer cap to receive the fabric, an innersleeve adapted to be inserted inside the fabric in said cap, and alsoadapted to receive the rib, the outer end of said sleeve being flared,an internal bead on said cap, said cover lying between said flared endand 15 said internal bead, substantially as specified 6. In a device ofthe character described, and in combination with the cover and rib,olf-an outer cover-rece'iving cap, an inner ribreceiving sleeve, saidsleeve being formed of resilient material and having a longitudinalslit, an vinternal bead Jformed on said outer cap, and a flared portionformed on the outer Aend of the sleeve beneath said bead, substarrtially as specified.

In testimony whereof, I have hereunto set :i my hand this 2nd day ofDecember, 1908.
